ABSTRACT:
A seal assembly for use in an engine, such as a scramjet engine, having a movable element, such as inlet cowl flap, is provided. The movable element has an outboard structural member which requires thermal protection. The seal assembly includes a sealing element and a support block for thermally isolating the outboard structural member and for supporting the sealing element. In a preferred embodiment, the sealing element comprises a rope seal having a tadpole construction.
